POW TRACKER ADJ 0,2% TO252-5 Description

The TLE 4251 is a monolithic integrated low drop voltage tracker in the very small SMD package PG-TO252-5-1. It is designed to supply e.g. sensors under the severe conditions of automotive applications. Therefore the device is equipped with additional protection functions against overload, short circuit and reverse polarity. Supply voltages up to 40 V are tracked to a reference voltage given to the adjust input via an external resistor. The output is able to drive loads up to 400 mA while it follows e.g. the 5 V output of a main voltage regulator within an accuracy of 0.5%. For loads up to 300 mA the tracking accuracy is 0.2%. The TLE 4251 can be switched in stand-by mode via the enable EN input which causes the current consumption to drop to very low values. This feature makes the IC suitable for low power battery applications.
